right or left. The valvulae or sheaths are two in number 

 and hollowed so as to receive the terebra, they are black 

 and covered with short hairs. From what I have said 

 above it is plain that when the egg is to be deposited the 

 sheath has to be used as well as the terebra, so that it seems 

 most probable that the egg passes down on the surface of 

 the terebra and is kept in place by the sheaths. 



Mr. Davies observed Rhyssa on the wing in June, seeing 

 both sexes. Sir C. Langham did not observe it till August 

 4th, but as there were several about he thinks they may 

 have probably been about before that date. In each case 

 the timber attacked by the Sirex was dead but not rotten. 



I desire to thank very heartily Sir Charles Langham 

 and Mr. CM. Davies for their most valuable help, without 

 which this paper could not have been written.

LEPIDOPTERA FROM EAST TYRONE. 



BY THOMAS GREER. 



In the April number of the Irish Naturalist for the year 

 1916 I contributed a short account of the Lepidoptera 

 occurring in this district. During the years 1918 and 1919 a 

 number of additional species were met with. I am 

 indebted to Dr. J. W. H. Harrison, of Newcastle-on-Tyne, 

 for the record of the tineid moth, Lemnatophila salicella, 

 hitherto unknown in this country. 



The following are the more interesting insects observed, 

 those marked thus * are new records for Ulster : — 



Euchloe cardaminis L. — A male with all wings of a pale yellow. May, 



1918 ; a female with both upper wings streaked with orange, near 



Grange, May, 1919. 

 Lycaena icarus Rott. — A fine male with orange marginal spots on upper 



side of lower wings ; July, 1919. 

 Ino statices L. — Tamnamore, two specimens at rest on flowers of Lychnis 



Flos-cucidi, May, 19 19. 

 Mlana bicoloria Vill. — Several examples at Ragweed bloom in Aug., 191 8 ; 



very rare in inland localities.
